SYSTEM OVERVIEW

ABOUT THE SYSTEM

Westcoat’s ALX™ Solar Reflective Finish System is a waterproof deck system that also meets the Cool Roof Requirements of California Title 24. It is reinforced with metal lath and is installed with a series of three separate white polymer-modified cementitious applications and sealed with

Westcoat’s Solar Reflective series of SC-10 Acrylic Topcoats, that utilize infrared (IR) pigments. The finished product weighs approximately 2½ lbs per square foot. This system gives plywood the look and the feel of concrete with a decorative appeal and also reduces the Urban Heat Island Effect and can lower the surface temperature.

Deck inspections and fire-rated coatings are more than just trending topics—they’re essential for safety, compliance, and long-term performance. To support architects, contractors, and property managers, we offer dedicated resources on both: a Deck Inspections page that explains SB 721 and SB 326 requirements, and a Fire-Rated Systems page detailing how Westcoat solutions meet today’s strictest building codes.
